Keeping your man-powered 2-wheeler secured doesn’t need to involve thick, heavy steel U-locks. Touted as “the lightest high-security bike lock on the market,” the innovative 560G Titanium Bike Lock seems to be a waaay better alternative.

Weighing in at just 560 grams (1.23 pounds), the lock is constructed of grade 5 titanium (one of the strongest alloys on the market – the same used in medical and aerospace applications), which means it can withstand serious attacks like chiseling, cutting, freezing, and even 48-inch bolt cutters. Its unique three-piece joints allow users to fold the whole thing, so it doesn’t take too much space, while a clever push-button mechanism lets you lock your bike, without the need of a key (you’ll use one to open it, though). Two 560G’s can be also be linked together, for extra reach.
